For the 3D printing multi-objective optimization task scheduling problem, problem model is established from three aspects of related definition, constraint conditions, and objective function, which lays foundation for subsequent research solution.

In recent years, people have paid more and attention to traditional manufacturing's environmental impact, especially in terms of energy consumption related emissions carbon dioxide. Except for adopting new equipment, production scheduling could play an important role reducing the total a manufacturing plant. Machine tools waste considerable amount because their underutilization. Consequently, s...

 This paper considers a bi-objective scheduling problem in a flexible manufacturing cell (FMC) which minimizes the maximum completion time (i.e., makespan) and maximum tardiness simultaneously. A new mathematical model is considered to reflect all aspect of the manufacturing cell. This type of scheduling problem is known to be NP-hard. To cope with the complexity of such a hard problem, a genet...

the research on project scheduling has widely expanded over the last few decades. the vast majority of these research efforts focus on exact and suboptimal procedures for constructing a workable schedule, assuming complete information and a static deterministic problem environment. project activities are scheduled subject to both technological precedence constraints and resource constraints, mo...
